wasm-opt-bug

Demo of what seems to be a bug in cargo wasi's invocation of wasm-opt: I can't seem to disable it for workspace packages.

Output of ./run.sh on my M1 Mac:

$> ./run.sh

Note that disabling wasm-opt only seems to work in a non-workspace package. Setting the same flag in the workspace Cargo.toml doesn't seem to work either, either with [workspace.metadata] or [workspace.package.metadata].
